IPC: G09G3/3233
Filed: 2021-04-22
Abstract: A foldable display panel and display device. The foldable display panel comprises a first display area (1) and a second display area (2) which are connected in a foldable manner. The foldable display panel comprises a first state and a second state. When the foldable display panel is in the first state, the first display area (1) emits light, and the second display area (2) does not emit light. When the foldable display panel is in the second state, both the first display area (1) and the second display area (2) emit light. The driving current density of the second display area (2) is configured to be greater than the driving current density of the first display area (1) when the first display area (1) and the second display area (2) are in the second state, and the aging speed of the second display area (2) is increased by using a larger driving current, and the aging speed of the first display area (1) is decreased by using a smaller driving current, such that the difference between the aging speeds of the first display area (1) and the second display area (2) can be reduced to the greatest extent, thereby ensuring the consistency of the display brightness of the first display area (1) and that of the second display area (2).

Abstract: A display panel and a drive method therefor, where when a gate electrode drive circuit (100) is scanning pixels line-by-line, a drive chip (300) controls a clock signal end to input a clock control signal (CK) into the gate electrode drive circuit (100), which causes a gate electrode scan signal (G(n)) to be output by the gate electrode drive circuit (100), and a data signal (Vd) output by a data signal end is controlled to be written to a pixel circuit (200) of a corresponding line. Wherein an active electrical level period of the clock control signal (CK) falls within an active electrical level period of the data signal (Vd), and a start time for the active electrical level period of the data signal (Vd) is at least 1-2 μs earlier than a start time for the active electrical level period of the clock control signal (CK). A period where the data signal (Vd) is written to a pixel circuit (200) does not overlap or overlaps an extremely small amount with a power source signal (ELVDD) fluctuation period, thereby preventing power source signal (ELVDD) fluctuation to affect writing of the data signal (Vd), and preventing a difference in brightness to be produced at a corresponding line of pixels.
